There's nothing geeky about this thread You tried to access a drive that probably has a format error which it clearly told you through push notification and you thought you could use command line access to circumvent that?

BlackBerry devices, all of them as far as I know, can not read/write to an NTFS formatted device directly via USB.
FAT, FAT32, and exFAT are the only supported formats.

If there is a computer hosting the NTFS device, and that computer has the BlackBerry Manager drivers installed, then the ability for the BlackBerry to manipulate data might be possible via USB to that computer. (and in some cases, Network Data or WiFi)

You were not able to create the "hdd" directory as your mount point. (First photo). This isn't even NTFS related.

See the second screenshot. Shared folder is read-only, so I created an "hdd" directory at /accounts/1000/shared/documents/ that appears in file manager. And further: "mount: Possible reason: Permission denied"
